Abstract
A display device includes a gate electrode, a gate insulating film, a first metal oxide layer having crystallinity, and a second metal oxide layer having non-crystallinity. The first metal oxide layer and the second metal oxide layer are sequentially laminated on a substrate. The first metal oxide layer and the second metal oxide layer are in contact with each other in all regions where the first metal oxide layer and the second metal oxide layer overlap each other. The first metal oxide layer at least partially has a first semiconductor region serving as a semiconductor. One of the first metal oxide layer and the second metal oxide layer at least partially has a conductor region made electrically conductive.
